One-way audio when calling multiple SIP

Report
Question

Hi, On one of our locations, I am having issues with one-way audio when I call
several phones with SIP/Phone_A&SIP/Phone_B&SIP/Phone_C. When I call the
phones individually, they work fine, so it's not a volume setting on the
phone. Also this setup has worked at other locations. Any idea's what to look for? Thanks in advance.
